  1. FCT / Laboratórios Associados – Gulbenkian, 30 July 2009 Technologies for biotelemetry in the Azores and the wider Atlantic Pedro Afonso, Ricardo Serrão Santos and the Biotelemetry WGroup

  2. Marine resource stewardship Ecosystem-based management Identification of critical habitats and habitat “hot spots” Knowledge of movements and interactionsw/ environment. Application and development of novel biotelemetry technologies

  3. Coastal spatial management: the usual suspect Where is the kl fish? Marine reserves can help conservation & fisheries sustainability if properly designed  habitat use & movements

  4. Size, location & spacing of reserves: habitat use & movements Acoustic tags Fixed receivers

  5. N=5 4 km 4 km 4 km 4 km 4 km

  6. Development of GIS modeling framework for MPA design: Integrating movements, abundance & habitat information

  7. Development of GIS modeling framework for MPA design: Integrating movements, abundance & habitat information ...in support of decision-making processes

  8. Seamount fisheries: moving deeper Connectivity scenarios Goraz: Adults in seamounts seeded by nurseries (EFH) inshore Boca-negra: Adult populations seeded by common pool

  9. Testing the island – seamount hypothesis Seamount fisheries: moving deeper ? • acoustic tagging of seamount species • deepwater (200-300m) acoustic stations w/ acoustic releases

  10. Integrating movements with synoptic information Seamount fisheries: moving deeper Deep scatering layer Benthic habitat mapping echo-sounding ROV video

  11. The wider, integrative scale: Question: role of Oceanic Ridges for pan-oceanic top predators? The Azores Region as critical habitat? Approach: simultaneously monitor the behaviour of diverse taxa using high-tech satellite biotelemetry

  12. Pan-Oceanic Migrants: why stop in the Azores? Sperm whale feeding behaviour Temperature-Depth recorders + Radio telemetry

  13. Pan-Oceanic Migrants: why stop in the Azores? Horizontal large-scale migrations of baleen whales

  14. Pan-Oceanic Migrants: why stop in the Azores? Feeding trips of Cory’s shearwater nesting adults GPS and satellite positioning

  15. Pan-Oceanic Migrants: why stop in the Azores? Mesoscale and pan-oceanic migrations of blueshark Vertical (TDR) and horizontal satellite tracking + Acoustic telemetry

  16. Pan-Oceanic Migrants: why stop in the Azores? Mesoscale and pan-oceanic migrations of Loggerhead turtles Vertical (TDR) and horizontal satellite tracking

  17. Technical Mitigation measures: Post-release behaviour of hooked turtles International longline fishery: new priorities, old problems Vertical (TDR) and horizontal satellite tracking

  18. Biotelemetry for the sustainable management Combining different technologies to resolve the various temporal and spatial scales of behaviors

  19. Biotelemetry for the sustainable management Submersibles, ROVs and scans for habitat mapping and surveying Synoptic description of the ocean
